Great case for those neat freaks! 5/7/2019 12:01:12 PM

Pros: This is a well built case with lots of great features. Fist off is wire management. They did a great job here. High quality velcro straps throughout. Well positioned case fan inserts allow for a multitude of options as well as water cooling.

Cons: I only have one thing to complain about and that's the wish for a little more room but it's my fault for not buying the next size up so nothing on the manufacturer side.

Overall Review: Definitely recommend this to someone looking for a sleek well designed case.

Lots of room 3/19/2019 5:49:14 PM

Pros: Looks great
No lights
Lots of space

Cons: Accessory Pack missing pieces

Overall Review: My "accessory pack" came with an improper amount of screws vs what appears on the contents, and did not contain any system board standoffs.

Awesome case with issues though. 3/2/2019 8:24:23 AM

Pros: Every part I bought fit correctly

Plenty of Space

Sides panel easy to remove

Plenty of spots for fans.

5 Hard Drive Spots

Came with all the screws and zip ties needed.

Cons: 1 Usb slot on the case had a bent pin when it arrived.

The power button led doesn't turn on unless the computer goes to sleep.

If you want to see your RBGs on the board or any other components, do not buy this case.

Silicon Power SSD can't be mounted correctly because of the placement of where the power connector needs to be.

Overall Review: I'm not a great reviewer especially this being my first build but I wanted a case with plenty of space and easy installation. A clear side panel would be a cool addition to this case if it's an option because the inside of the case is well designed.

Best case I have ever used or seen 2/1/2019 2:18:15 PM

Pros: Very nice build quality and great sound dampening on all sides. Wide open chamber allows for good airflow and expansion into liquid cooling. Honestly I have no idea why they even made an S2 because this one is just so good already. Cases no longer come with a side mount fan and I think that is just terrible. I chose this because it does have a mounting position for the fan. I have a fan that pulls air out there and it keeps my GPU 10 degrees cooler than otherwise without it. Plus when you give the air an avenue to escape the case the other components won't get as hot either. The front plate does not restrict airflow at all either.

Cons: Fans that came with it are ok at best. I swapped 1 noctua 120mm fan in place of the 2 140mm fans that came with it and it is quieter while performing better. I wish they just didn't come with it and instead discount the case. No USB 2 or USB c in the top is a pretty big oversight.

Overall Review: I highly recommend this case to anyone. It is the best value case I found after literally dozens of hours of searching.

Cons: is huge definitly a floor or wall shelf tower not for on top of desk

Overall Review: if your new to pc building this has lots of room for components and mounting any option fits really also easy to get hands in and out installing components

Great case solid 4.5 for what I want 10/14/2018 1:29:45 PM

Pros: You can make this into a great dust controled case
Quiet
Plenty of air flow
Plenty of space
Looks nice

Cons: No optical drive mount (I wouldn't want one in standard position anyway because it would block one of my fans)
Side window is plastic and I can't find the glass panel upgrade anywhere in U.S.A.
Bottom filter comes out the back...dumb dumb dumb....should come out the front!
No dust filter for top (if you remove sound proof panels)

Overall Review: I've had this case since 2016 and I love it...I would love it more if I could find the tempered glass side panel but alas I cannot find one in the USA. My case has a 240mm AIO as front intake, one more 120mm fan on front intake, bottom stock fan intake, rear stock fan exhaust. This setup works great. I use strategically placed painters tape to seal off any openings with the exception of the intake (front/bottom) and the exhaust.

Most cases have way too many holes, hex pattern vents, just letting tons of dust inside. One of the main reasons I got this case is because it has less holes in it and it is fairly easy to cover the holes it does have. My components stay cleaner than any other case I have had in the past. Temps while gaming: cpu 45-55 spike to 60 on occasion, gpu 30-36 maybe 40 on occasion (granted it's a beast of a card with 3 fans EVGA GTX 1080Ti FTW3 acts like a heat pump removing any hot air maybe, stays quiet rarely ever hear it, I do hear the Corsair AIO spin up when gaming).------------------BTW I tried top exhaust for the cooler and it doesn't work well so I moved back to front intake ....much MUCH better and more quiet too!

I often look at new flashy cases, tempted by the new fancy glass and lights but they always have too many entries for dust so I'll stick with this one ...just wish I could get the glass panel upgrade!
